  • Hydrodeoxygenation of a Model Compound of Pyrolysis Oil Using Molybdenum Catalysts on Activated Carbon Supports. Nick Dunn Union College. Advisors: Dr. Brian Frederick and Dr. Clayton Wheeler 0.5g of the sulfided catalyst is added to 3.00mL of the model compound guaiacol in 100mL decalin. The mixture is heated up to 300C and put under 50 bar H 2 pressure for 4 hrs, with periodic samples taken
  • Slide 6
  • Converting Lignin into Nano Structured Carbon Materials Alden Earle Ramapo College of New Jersey Advisor: Dr. David Neivandt Lignin is an underused byproduct of the Kraft pulping process that is largely burnt for fuel. It is the 2 nd most plentiful organic polymer in the world. Nano-carbon is used for numerous applications due to its high electrical and thermal conductivity, high tensile strength, surface area etc. However, it is typically expensive to mass produce and employs non-renewable feedstocks. A proprietary method of converting lignin into nano structured carbon materials is being developed. Significant room exists for optimization of the process.

  • The Study of the Total Pressure during the Acid Hydrolysis with SS Alex A. Haluska Syracuse University Advisor: Dr. Adriaan van Heiningen & Graduate Student, Rory Jara The Study of the Total Pressure during the Acid Hydrolysis with SO 2 as a Function of Temperature and SO 2 Alex A. Haluska Syracuse University Advisor: Dr. Adriaan van Heiningen & Graduate Student, Rory Jara 1% xylan, 1% acetic acid, 98% water to simulate Hot Water Extract (HWE) 1% xylan, 1% sodium acetate, 98% water to simulate Near Neutral Extract (NNE) Sulfur dioxide (SO 2 ) is a gas that can be used as a catalyst for the hydrolysis of hemicelluloses oligomers SO 2 Reactor SO 2 trap H2O2H2O2 H 2 SO 4 Xylan e Scale SO 2 + H 2 O 2 H 2 SO 4

  • Utilizing Tangential Flow Ultrafiltration for the Concentration of Hemicellulose Extracts Rob Jonson Kansas State University Advisor: Dr. Peter van Walsum & Graduate Student Sara Walton Hot water and green liquor hemicellulose extracts must be concentrated before they can be fermented. Filtration might be optimized by developing a relationship between extraction intensity and the extracts molecular weight distribution.

  • Separation and Classification of High-Value Chemicals in Picea species Annemarie Nauert University of Missouri Advisors: Drs. Cole & Fort Graduate Student: Regan LeBlanc Separation of secondary metabolites found in bark by liquid-liquid extractions Classification based on antioxidant activity, phenolics, and flavonoids content Effort to use most environmentally-conscious solvents

  • Bioprospecting for an enzyme that cleaves ether bonds between lignin and hemicellulose in hardwoods Rosie Ochoa- Sacramento City College Advisors: Dr. Nancy G. Kravit Environmental colonies Environmental samples and ATCC cultures were screened for their ability to cleave the ether bond between xylan (primary sugar in hardwood hemicellulose) and 4- Methylumbelliferone. Positive cultures were grown and tested in different media and growth conditions to optimize enzyme expression.
  • Slide 11
  • Acid springing and extraction using trioctylamine Audrey Polifka Kansas State University Advisor Dr. Peter van Walsum Goal is to extract acetic acid from a model solution using trioctylamine (TOA) as the extractor and octanol as the diluent. Testing variables such as concentrations of organic & aqueous phases, ratio of organic to aqueous, temperature of reaction, and pH of aqueous phase. Also determining recyclability of TOA to be used in economic analysis.

  • Extraction of Shikimic Acid from foliage of the Picea Species Alexander Shaffer Youngstown State University Advisors: Drs. Barbara Cole & Ray Fort * Graduate Student: Gedivinne Nilmini * HS Student: Mark Rowe Goal: Minimize tree waste in an optimized industrial ready process that maximizes yield of shikimic acid at a low cost while maintaining other industrial operations at their current capacity. Initial Findings: Higher temperature = Better Extraction Crushing needles improves results Length of extraction impacts extraction results 100 C 140 C 100 C140 C Crushed Needles / Whole Needles B = Basic C = Crushed H = Hour W = Whole
